Don't Starve Together (Steam AppID 322330) through build 747465 contains a memory-corruption vulnerability in the native persistent-string decoder that allows a remote attacker operating a public dedicated server to crash a victim's game client by publishing crafted world_gen_data with an invalid Klei persistent blob header length. Attackers can craft a malicious public lobby server listing that, once viewed or selected by the victim, triggers client-side decoding of the attacker-controlled data to corrupt native memory and cause a remote denial of service.
